man city right and left backs are their achilles heel. zabaletta
and bridge. slow, useless in attack, mediocre defenders at
best.
i cant imagine a top club like city relying on this
quality of defenders. not say their centerbacks are also top
class. man c defense is always shaky. they try to cover it up by
scoring more goals than they concede.
That's the problem when you have an owner with huge bags of
money. He will see himself as having the right to play Football
Manager with the cheat code on. 
Everyone has been pointing out the same thing - Man City's
strikeforce is awesome, but their defensive cover is woeful.
All Man City has to do is to get a couple of good defenders
costing maybe 20 million pounds total, and recall Joe Hart as the
backup goalie for Shay Given.
Problem is, all that money is obscuring what should be plainly
obvious.
